Question

What is “controller.controllers” in Ember.js ?

It seems that

this.getPath("controller.controllers") 

in the view returns App.router.
It’s very usefull but I’d like to understand what I’m doing 🙂

When calling initialize on your Ember.Application, all controllers are instantiated and set on the router. The controller in turn also gets some properties injected, as implemented here. As you can see, the controllers property is a reference to the router.

Ember.Application.registerInjection({
  name: 'controllers',
  injection: function(app, router, property) {
    if (!/^[A-Z].*Controller$/.test(property)) { return; }

    var name = property.charAt(0).toLowerCase() + property.substr(1),
        controller = app[property].create();

    router.set(name, controller);

    controller.setProperties({
      target: router,
      controllers: router,
      namespace: app
    });
  }
});
